I have (on more than one occasion) rear ended somebody's car while attempting to stop in the rain. It's called hydroplaning, which is what happens when your tires drive over wet pavement or standing water and lose contact with the road surface, resulting in a loss of traction and an inability to steer the car.
I think it's possible the Dedmond daughter was driving, saw Asha, actually wanted to stop and help, but because of the wet road she ended up sliding directly into Asha and could not stop.
Again, this is all my opinion but I have a hard time thinking this is a case of grooming when the Dedmon's daugther's DNA is on that book bag. Most predators act alone, keep the secret to their grave or until they are caught. They would not involve their teenage daugther or spouse. And they wouldn't ask a victim to trek along a highway at 3 AM. Too risky and doesn't make sense.
There's also a lot of red herrings in this case including
1. The sleepover. I keep seeing this cited as a potential clue to the case, and I really just don't see it. I'm not attempting to offend anyone here, but I'm black and I can tell some of y'all aren't familiar with the black family dynamic in small towns. The majority of black families in the south are large and tight knit. Lots of cousins in neighboring towns. In my town, if you're black, there's a greater than 90% chance that either I know you and your relatives, or I AM a relative. Sleepovers and extended stays at one another's homes are extremely, extremely common. I don't consider it the least bit strange that Asha was attending one of these, it was probably a very regular occurance.
2. The basketball game. I don't think this has any bearing at all.
3. Why she left the house. Puzzling? Yes. Strange? For sure. But Asha was 9. There's really no telling why she left and we don't have any good evidence of grooming or that she was coaxed to leave by someone. I think at this point it's possible and maybe even likely that her leaving the home, and whatever happened to her are two separate issues.
